Testing Android project with jar dependecies

Question

My Android project has a few jar libraries as dependencies. Alone, it compiles and works well. I wrote a little test project but running it I don't get any result (no tests passed or failed) nor any error, but in the logcat's output there are warnings like this:

06-06 14:55:43.533: INFO/dalvikvm(7049): Failed resolving Lcom/adwhirl/adapters/InMobiAdapter; interface 315 'Lcom/inmobi/androidsdk/InMobiAdDelegate;'

As you can see seems that there are problem exporting the libraries, infact I get an error like that for every library. I read in this blog post that to get it to work, it should be enough to export all the libraries in the main project, but for me didn't works. Any other idea?

Answer 1

what worked for me was - in 'Order and Import' section bringing my jar file up

Answer 2

Have you tried to put the jars in libs intead than lib ?

Answer 3

Go to your project that uses .jar files (i.e. project under test). Click right button -> Properties-> Java Build Path -> Order and Export -> check libraries there
